Wow, that brings me back......ahhh memories.
My EX would go through periods of moderation. Some periods were pretty long in fact. I must have heard every proclamation in the book.
Once upon a time, I believed him and was disappointed at every relapse into binge drinking. I think the grander the proclimations the deeper the disappointment and the deeper my disappointment the angrier he was at me when he finally gave in and went on a bender.
I remember when he made his announcements (and believe me he would walk in like Moses with tablets in hand some times to proclame his decision)were always about how great he was and how he could take control of his life and the relapses were always about how unsupportive I was of him and how unforgiving I was. I considered permanently installing a soapbox in the living room because he spent so much time on one.
You asked if what your A says is quacking.....and it most certainly is. When you see it as just his addiction playing games, you can detach from his behavior. No more disappointment over the backslides and no more fall guy when he doesn't stay long on his "one glass" path. Bravo to you!!
If moderation were that easy, he would be doing it everyday without declaring it. Addiction has him and thus "just one" can't be a reality.
Stay strong. You see his BS a mile away!!
